The Aquatic Life Twist-In 100 GPD 4-Stage Reverse Osmosis Deionization (RODI) filtration systems are very compact water purification solutions that efficiently combine reverse osmosis RO and DI technology with our quick and easy to change twist-in replacement filter cartridges. The new twist-in media cartridge design makes filter changes simple, easy and clean – no tools required and no mess! The twist-in cartridges can be easily changed in only seconds with just a quarter turn and without contact with used filter material, and the supply water to the unit does not have to be turned off to replace any cartridge.
STAGE 1 – TWIST-IN SEDIMENT FILTER CARTRIDGE: Recommend replacing every 6 months. The first stage of your RO unit is a 5-Micron Sediment Filter that traps sediment and other particulate matter like dirt, silt and rust which will affect the taste and appearance of your water.
STAGE 2 – TWIST-IN CARBON BLOCK FILTER CARTRIDGE: Recommend replacing every 6 months. The second stage of your RO unit is a Carbon Block Filter. The Activated Carbon in the filter reduces chlorine by up to 99% and conditions the water prior to the RO Membrane.
STAGE 3 – TWIST-IN RO MEMBRANE FILTER CARTRIDGE: Recommended replacing every 1-2 Years. The RO Membrane reduces impurities known as Total Dissolved Solids (TDS) from the water down to 1/10,000 of a micron, reducing arsenic, lead, parasitic cysts, copper and more.
STAGE 4 – TWIST-IN MIXED BED COLOR CHANGING RESIN DEIONIZATION CARTRIDGE: Replace filter when resin changes color completely to amber. When all resin has changed color, it is time to replace the DI filter.
